A disappointed Coles shopper has been mocked after complaining about the quality of the store’s beef burgers.

The shopper complained on the supermarket’s Facebook page about opening a pack of Coles Beef BBQ burgers she had purchased that afternoon to find “a chunk of meat” instead of 10 individual patties.

“Coles, just wondering … am I meant to carve my own burger patties out of this chunk of ‘meat’???” Cushla Johnstone asked on a post accompanied by pictures of the product.

“Just a little confused considering I was expecting 10 individual burger patties … not one pattie for Fred Flinstone (sic).”

Coles was quick to apologise for the product not being up to standard: “We expect our products to be of a high quality at all times, so we apologise this wasn't the case for you today,” the store replied.

“We'll pass this feedback on to our National Quality Team so they're aware of this, and in line with our 100% Satisfaction Guarantee on all Coles Brand products, please feel free to return to any of our stores with either your receipt or the empty packaging for a full refund. We're very sorry for the disappointment.”
